Abstract
Description
【0001】
【発明の属する技術分野】
本発明は、インクジェットプリンターに好適に使用できる水性インクに関する。
【0002】
【従来の技術】
従来から、紙面上でのインクの耐水性、定着性を向上させる為に、色材として水不溶性色材の顔料等を用いる試み、又は染料に凝集機能や水不溶化機能を持たせる試みがある。例えば、色材として顔料を用い、分散安定剤として三元共重合体等の分散剤を用いたインク(特許文献1参照)、染料の対イオンとしてアンモニウム塩を用いたインク(特許文献2)、あるいは染料と分岐状アミン系化合物を含有することで凝集機能や水不溶化機能を持たせたインク(特許文献3)が提案されている。
【0003】
しかし、顔料、分散剤を用いた場合、耐擦過性、耐マーカー性において不十分である場合が多い。又、染料に凝集機能や水不溶化機能を持たせた場合、染料の初期の溶解性は良好であっても、インク中から徐々にアンモニアが揮発することにより染料の溶解性が低下したり、インク中にアニオン性とカチオン性を同時に含むため、インクの長期保存安定性が低下する場合がある。又、アニオン性ポリマー含有インクとカチオン性ポリマー含有インクを互いに接触させて印刷媒体上に適用する試みがあるが(特許文献4参照)、耐水性において境界にじみが生じる等の問題がある。

【発明の実施の形態】
次に好ましい実施の形態を挙げて本発明をさらに詳細に説明する。
本発明で使用する樹脂は、インクが紙等の記録材に付与された後は、記録材に対して色材を定着させる作用をするものであり、樹脂は1種類のホモポリマーでもよいが、ポリマーの物性を最適化すべく、それぞれ少なくとも1種類の親水性ブロック及び疎水性ブロックからなり、各ブロックがビニルエーテル系重合体からなる共重合体であり、親水性ブロックを形成するビニルエーテル系ポリマーにはアニオン性基が存在するものが好ましい。さらに好ましくは、共重合体の形態はブロックポリマー、グラフトポリマー、グラジュエーションポリマー等である。より好ましいのはブロック共重合体であり、ブロック共重合体はそれぞれ1種の親水性ブロック及び疎水性ブロックからなる共重合体、いずれか一方が1種、他方が2種のブロック共重合体等のブロックの存在態様は種々あるが、いずれでもよい。
【0008】
上記樹脂を形成する、疎水性を有するビニルエーテル類のブロックとしては、下記一般式(1)で示される繰り返し単位構造を有するブロックが好ましい。
−(CH2−CH(OR1))− (1)
上記の一般式(1)において、R1は、アルキル基、アルケニル基、シクロアルキル基またはシクロアルケニル基のような脂肪族炭化水素基、フェニル基、ピリジル基、ベンジル基、トルイル基、キシリル基、アルキルフェニル基、フェニルアルキレン基、ビフェニル基、フェニルピリジル基等のような、炭素原子が窒素原子で置換されていてもよい芳香族炭化水素基を表わす。また、芳香環上の水素原子は、炭化水素基で置換されていてもよい。R1の炭素数は1〜18が好ましい。
【0009】
またR1は、−(CH(R2)−CH(R3)−O)p−R4若しくは−(CH2)m−(O)n−R4で表される基でもよい。この場合、R2及びR3は、それぞれ独立に水素原子またはメチル基を表わし、R4は、アルキル基、アルケニル基、シクロアルキル基またはシクロアルケニル基のような脂肪族炭化水素基、フェニル基、ピリジル基、ベンジル基、トルイル基、キシリル基、アルキルフェニル基、フェニルアルキレン基、ビフェニル基、フェニルピリジル基等のような、炭素原子が窒素原子で置換されていてもよい芳香族炭化水素基(芳香環上の水素原子は、炭化水素基で置換されていてもよい)、−CO−CH=CH2、−CO−C(CH3)=CH2、−CH2−CH=CH2、−CH2−C(CH3)=CH2を表わし、これらの基のうちの水素原子は、化学的に可能である範囲で、フッ素、塩素、臭素等のハロゲン原子と置換されていてもよい。R4の炭素数は1〜18が好ましい。pは1〜18が好ましく、mは1〜36が好ましく、nは0または1であるのが好ましい。
【0010】
R1及びR4において、アルキル基またはアルケニル基としては、例えば、メチル、エチル、プロピル、イソプロピル、n−ブチル、sec−ブチル、t−ブチル、ペンチル、へキシル、ヘプチル、オクチル、ノニル、デシル、ドデシル、テトラデシル、ヘキサデシル、オクタデシル、オレイル等であり、シクロアルキル基またはシクロアルケニル基としては、例えば、シクロプロピル、シクロブチル、シクロペンチル、シクロへキシル、シクロオクチル等である。
【0011】
次に、親水性を有するビニルエーテル類のブロックとしては、下記一般式(2)で選ばれる繰り返し単位構造を有するブロックが好ましい。
−(CH2−CH(OR5))− (2)
上記一般式(2)において、R5は、−(CH2−CH2−O)k−R6、−(CH2)m−(O)n−R6、−R7−X、−(CH2−CH2−O)k−R7−X、−(CH2)m−(O)n−Xで表わされる基である。この場合、R6は、水素原子、炭素数1から4までの直鎖または分枝状のアルキル基、及び−CO−CH=CH2、−CO−C(CH3)=CH2、−CH2−CH=CH2、−CH2−C(CH3)=CH2を表わし、R7はアルキレン基、アルケニレン基、シクロアルキレン基またはシクロアルケニレン基のような脂肪族炭化水素基、フェニレン基、ピリジレン基、ベンジレン基、トルイレン基、キシリレン基、アルキルフェニレン基、フェニレンアルキレン基、ビフェニレン基、フェニルピリジレン基等のような、炭素原子が窒素原子で置換されていてもよい芳香族炭化水素基(芳香環上の水素原子は、炭化水素基で置換されていてもよい)を表わし、これらの基のうちの水素原子は、化学的に可能である範囲で、フッ素、塩素、臭素等のハロゲン原子と置換されていてもよい。Xは、カルボン酸基、スルホン酸基、リン酸基から選ばれるアニオン性を有する基を表わす。R7の炭素数は1〜18が好ましい。kは1〜18が好ましく、mは1〜36が好ましく、nは0または1であるのが好ましい。
【0012】
下記に、上記で説明した繰り返し単位を含むモノマー(I−a〜I−o)及びポリマー(II−a〜II−e)の構造を例示するが、本発明に用いられるポリビニルエーテル構造は、これらに限定されるものではない。
【0013】
【化1】
【0014】
【化2】
【0015】
更に、ポリビニルエーテルの繰り返し単位数[上記(II−a)〜(II−e)においては、m、n、l]は、それぞれ独立に、1〜10,000であることが好ましい。また、その合計が[上記(II−a)〜(II−e)においては、m+n+l]が、10〜20,000であることがより好ましい。また、数平均分子量で、500〜20,000,000ものが好ましく、1,000〜5,000,000のものがより好ましく、2,000〜2,000,000のものが最も好ましい。また、これらポリビニルエーテルは、それを他の高分子にグラフト結合させたもの使用しても良いし、他の繰り返し単位構造と共重合されたものを使用しても良い。
【0016】
ビニルエーテル系ポリマーブロックを有する共重合体の合成方法は、特に限定されないが、カチオンリビング重合法を用いることにより長さ(分子量)を正確に揃えたホモポリマーや2成分以上のモノマーからなる共重合体、さらにはブロックポリマー、グラフトポリマー、グラジュエーションポリマー等の様々なポリマーを合成することができる。また、ポリビニルエーテルは、その側鎖に様々な官能基を導入することができる。
【0017】
本発明のインクジェットプリンター用水性インク、少なくとも色材と前記の樹脂を含むものである。樹脂は、親水性ブロック中のアニオン性基をアンモニア又はアミンで中和してこれらの塩として使用することが画像形成後の耐水性等を向上させるので好ましい。該アニオン性基のカウンターイオンとして、アルカリ金属(Na、K,等)を用いた場合、画像形成後の耐水性、例えば、印字物の一部に水分が付着した場合に、水分が接触した印字物の部分と、接触していない部分との間での境界にじみ等の問題が生じる場合がある。
【0018】
又、水性インクにはアルミニウム又はアルミニウムイオンを存在させることが好ましい。その場合、樹脂とアルミニウム(アルミニウムイオン)とのモル比は1:5〜10000:3が好ましく、更に好ましいモル比は100:6〜1000:3が好ましい。樹脂に対してアルミニウムのモル比が少なすぎると、本発明のインクによって形成される画像の耐擦過性、耐水性、耐マーカー性等、インクの記録材への定着性が十分でない場合があり、また、樹脂に対してアルミニウムのモル比が多すぎると、水性インクの吐出安定性が低下する場合がある。アルミニウム以外のアルミニウム化合物としては、有機及び無機の化合物が使用される。例えば、アルミナ、水酸化アルミニム、トリプロピルアルミニウム、トリイソプロピルアルミニウム、チーグラーナッタ触媒のアルミニウム化合物等が挙げられる。
【0019】
水性インクを上記の構成にすることにより、インクの吐出安定性が良く、画像を形成した際の定着性、耐水性、耐擦過性が向上する。これは、樹脂中の少なくとも1種の親水性ブロック部がアニオン性基を有することにより、水媒体中での分散安定性が良好となる。更に、該アニオン性基をそのカウンターイオンとしてのアンモニウムイオン若しくはアミン塩として用いることにより、印字後はアンモニウム或いはアミンが揮発し、親水性を失うため、耐水性が向上すると考えられる。また、樹脂が有するアニオン部分若しくはエーテル部分とカチオン性を有するアルミニウム、例えば、アルミニウムイオン、アルミナ、水酸化アルミニウム等とが作用して樹脂が凝集することにより定着性、耐擦過性が向上すると考えられる。
【0020】
尚、ビニルエーテル系ポリマーの製造において、有機アルミニウム化合物を触媒として使用する場合には、樹脂とアルミニウムを前記のモル比にするために、ポリマーを精製してアルミニウム含有量を低減することが好ましく、酸性水溶液による分液、透析、限外濾過、再沈、吸着剤による吸着等があるが、これに限定されるものではない。また、ポリマー中の残存アルミニウム量が判る場合には、このアルミニウム量も含めたモル比を設定する。
【0021】

【0031】
以上の色材と樹脂とのインク中における質量比率は、固形分比で1:0.01〜1:2であることが好ましい。樹脂量が少なすぎると、本発明のインクによって形成される画像の耐擦過性、耐水性、耐マーカー性等、インクの記録材への定着性が十分でない場合があり、また、樹脂量が多すぎると、水性インクの粘性が高くなり、水性インクの吐出安定性や耐目詰まり性が低下する場合がある。
【0032】
本発明の水性インクは、前記の色材及び樹脂を分散又は溶解させる液媒体が必要であり、該液媒体は少なくとも水溶性の有機溶剤を含んでいてもよい。好ましくは水と水溶性有機溶剤との混合溶剤を水性インクの液媒体として使用する。本発明において液媒体に占める水溶性有機溶剤の割合は、例えば、5〜50質量%が好ましく、更に好ましくは10〜40質量%である。
【0033】
上記水溶性有機溶剤は、本発明のインクに、ノズル部分での乾燥による水性インクの固化を防止するために使用するものであって、具体的には、炭素数1から4のアルキルアルコール類(例えば、メチルアルコール、エチルアルコール、n−プロピルアルコール、イソプロピルアルコール、n−ブチルアルコール、sec−ブチルアルコール、tert−ブチルアルコール等);ケトン又はケトアルコール類(例えば、ジメチルホルムアミド、ジメチルアセトアミド等のアミド類、アセトン、ジアセトンアルコール等);エーテル類(例えば、テトラヒドロフラン、ジオキサン等);ポリアルキレングリコール類(例えば、ポリエチレングリコール、ポリプロピレングリコール等);アルキレン基が2〜6個の炭素原子を含むアルキレングリコール類(例えば、エチレングリコール、プロピレングリコール、ブチレングリコール、トリエチレングリコール、1,2,6−ヘキサントリオール、チオジグリコール、ヘキシレングリコール、ジエチレングリコール等);多価アルコール等のアルキルエーテル類(例えば、エチレングリコールメチルエーテル、エチレングリコールエチルエーテル、トリエチレンモノメチルエーテル、トリエチレングリコールモノエチルエーテル等)、さらにはN−メチル−2−ピロリドン、2−ピロリドン、1,3−ジメチル−2−イミダゾリジノン等が挙げられる。
【0034】
特に好ましい水溶性有機溶媒は、グリセリン、多価アルコール(例えば、ジエチレングリコールやエチレングリコール等)であり、グリセリン以外の多価アルコールとしては、例えば、ジエチレングリコール、エチレングリコール、ポリエチレングリコールやプロピレングリコール等が挙げられる。水性インク中にはこれらの水性有機溶媒を2種類以上混合して用いてもよい。
【0035】
本発明のインクは上記水溶性有機溶剤とともに水を含有する。液媒体に占める水の割合としては、例えば、50〜100質量%、更には60〜100質量%であることが好ましい。また、水としては純水又はイオン交換水を用いることが好ましい。
【0036】
本発明のインク中における色材の水性インク全質量に占める割合は、例えば、0.1〜20質量%、さらには1〜10質量%であることが好ましい。色材の量が1質量%未満では印字画像に十分な画像濃度が得られず、色材の量が10質量%を超えると、ノズルにおける目詰り等の吐出安定性が低下するだけで、画像の濃度が特別向上するわけでもない。
【0037】
また、本発明の水性インク中における前記樹脂の水性インク全質量に占める割合は、例えば、0.001〜40質量%、更には0.01〜20質量%であることが好ましい。前記樹脂の量が0.01質量%未満では得られる画像の耐擦過性、耐マーカ性等が低下し、一方、前記樹脂の量が20質量%を超えると、水性インクの粘性が高くなり、ノズルにおける水性インクの目詰り等の吐出安定性が低下する。
【0038】
尚、本発明の水性インクには、前記成分以外にも、例えば、界面活性剤、pH調整剤、酸化防止剤、防黴剤等各種の添加剤を添加してもよい。また、本発明の水性インクの粘度は25℃において1.0mPa・s〜5.0mPa・sであることが好ましい。
【0039】
【実施例】
次に実施例及び比較例を挙げて本発明をさらに具体的に説明するが、本発明は、その要旨を越えない限り、下記実施例により限定されるものではない。尚、以下の記載で「部」又は「%」とあるものは特に断らない限り質量基準である。又、以下の実施例において樹脂の分子量及び分子量分布はGPC(Gel Permeation Chromatography:東ソー社製HLC−8220GPCを使用)、樹脂の同定はNMR(ブルカー・バイオスピン社製DPX400を使用)により、アルミニウムの濃度はICP発光分析装置(誘導結合プラズマ発光分析装置)(セイコーインスツルメンツ社製SPS 1700HVを使用)により、pHはpHメーター(堀場製作所製 カスタニーACTpHメーターD−24を使用)を用いて測定した値である。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to an aqueous ink that can be suitably used for an inkjet printer.
[0002]
[Prior art]
Conventionally, in order to improve the water resistance and fixability of ink on paper, there have been attempts to use a pigment of a water-insoluble coloring material or the like as a coloring material, or to impart a coagulation function or a water-insolubilizing function to a dye. For example, an ink using a pigment as a coloring material and a dispersant such as a terpolymer as a dispersion stabilizer (see Patent Document 1), an ink using an ammonium salt as a counter ion of the dye (Patent Document 2), Alternatively, an ink (Patent Document 3) has been proposed in which a dye and a branched amine compound are included to have a coagulation function and a water insolubilization function.
[0003]
However, when a pigment or a dispersant is used, the scratch resistance and the marker resistance are often insufficient. In addition, when the dye has an aggregating function or a water-insolubilizing function, even if the initial solubility of the dye is good, the solubility of the dye is reduced by gradually evaporating ammonia from the ink, Since the ink contains both anionic and cationic properties, the long-term storage stability of the ink may be reduced. Further, there is an attempt to apply an anionic polymer-containing ink and a cationic polymer-containing ink on a print medium by bringing them into contact with each other (see Patent Literature 4), but there is a problem such as boundary blurring in water resistance.

[0015]
Further, the number of repeating units of the polyvinyl ether [in the above (II-a) to (II-e), m, n, l] is preferably independently 1 to 10,000. It is more preferable that the sum [m + n + 1 in the above (II-a) to (II-e)] is 10 to 20,000. Further, the number average molecular weight is preferably from 500 to 20,000,000, more preferably from 1,000 to 5,000,000, and most preferably from 2,000 to 2,000,000. These polyvinyl ethers may be used by grafting them to another polymer, or may be those copolymerized with other repeating unit structures.
[0016]
The method for synthesizing the copolymer having a vinyl ether-based polymer block is not particularly limited, but a homopolymer or a copolymer composed of two or more monomers whose length (molecular weight) is precisely adjusted by using a cationic living polymerization method. Further, various polymers such as block polymers, graft polymers, and gradient polymers can be synthesized. In addition, various functional groups can be introduced into the side chain of polyvinyl ether.
[0017]
The aqueous ink for an inkjet printer of the present invention contains at least a coloring material and the above-mentioned resin. It is preferable to use the resin as a salt thereof by neutralizing the anionic group in the hydrophilic block with ammonia or an amine, since the water resistance after image formation is improved. When an alkali metal (Na, K, etc.) is used as the counter ion of the anionic group, the water resistance after image formation, for example, when moisture adheres to a part of the printed matter, the print contacted with moisture. In some cases, a problem such as blurring of a boundary between an object portion and a non-contact portion may occur.
[0018]
Preferably, aluminum or aluminum ions are present in the aqueous ink. In that case, the molar ratio of the resin to aluminum (aluminum ion) is preferably 1: 5 to 10,000: 3, and more preferably 100: 6 to 1000: 3. If the molar ratio of aluminum to the resin is too small, the abrasion resistance of the image formed by the ink of the present invention, water resistance, marker resistance, and the like, the fixability to the recording material of the ink may not be sufficient, If the molar ratio of aluminum to resin is too large, the ejection stability of the aqueous ink may decrease. Organic and inorganic compounds are used as aluminum compounds other than aluminum. For example, alumina, aluminum hydroxide, tripropylaluminum, triisopropylaluminum, an aluminum compound of a Ziegler-Natta catalyst and the like can be mentioned.
[0019]
When the aqueous ink has the above-described configuration, the ejection stability of the ink is good, and the fixability, water resistance, and scratch resistance when an image is formed are improved. This is because dispersion stability in an aqueous medium is improved because at least one kind of hydrophilic block portion in the resin has an anionic group. Further, by using the anionic group as an ammonium ion or an amine salt as a counter ion thereof, ammonium or amine volatilizes after printing and loses hydrophilicity, so that water resistance is considered to be improved. Further, it is considered that the anion portion or the ether portion of the resin and aluminum having a cationic property, for example, aluminum ion, alumina, aluminum hydroxide and the like act to coagulate the resin, thereby improving the fixing property and the abrasion resistance. .
[0020]
In the case where an organoaluminum compound is used as a catalyst in the production of a vinyl ether-based polymer, it is preferable to reduce the aluminum content by purifying the polymer in order to adjust the molar ratio between the resin and aluminum. Separation with an aqueous solution, dialysis, ultrafiltration, reprecipitation, adsorption with an adsorbent and the like are not limited thereto. If the amount of residual aluminum in the polymer is known, the molar ratio including this amount of aluminum is set.

After returning the system to room temperature, 12 mmol of 1-isobutoxyethyl vinyl ether, 16 mmol of ethyl acetate, 0.1 mmol of 1-isobutoxyethyl acetate, and 11 ml of toluene were added, and when the temperature in the system reached 0 ° C., ethyl was added. Polymerization was started by adding 0.2 mmol of aluminum sesquichloride, and component A of the triblock polymer was synthesized. The molecular weight was monitored in a time-division manner using GPC, and after the polymerization of the component A was completed, the synthesis was carried out by adding 12 mmol of 2-methoxyethyl vinyl ether, which was the component B, and then using GPC in the same manner as described above. After the completion of the polymerization of the B component, the synthesis was carried out by adding 12 mmol of 4- (2-vinyloxyethoxy) -ethylbenzoate, which is the C component. This was done by adding a 3% ammonia / methanol solution. The obtained triblock polymer was identified using NMR and GPC, and a satisfactory spectrum was obtained in both cases (number average molecular weight (standard polystyrene conversion) Mn = 3.7 × 10 Four , Mn / Mw = 1.3 (Mw: weight average molecular weight (standard polystyrene conversion))).

In order to adjust the amount of aluminum in the obtained resin, liquid separation was performed with a 0.6N aqueous hydrochloric acid solution, and purification was performed so that the molar ratio between the resin and aluminum became a value shown in Table 1. The number of moles of aluminum is a value obtained from the concentration of aluminum.
[0042]
The ester portion of the C component of the resin was hydrolyzed in potassium hydroxide / methanol to convert to the carboxylic acid form. Further, potassium ions were removed by dialysis and an ion exchange resin, and neutralized by dropwise addition of an aqueous solution of ammonium hydroxide, thereby changing the counter ions of the carboxylic acid to ammonium ions. The pH of the obtained resin was 8.0.
[0043]
(ii) Preparation of block polymer [2]
A block polymer was prepared in the same manner as in the block polymer [1] except for adjusting the counter ion of the carboxylic acid of the component C. The counter ion of the carboxylic acid of the component C was neutralized by dropwise addition of an aqueous sodium hydroxide solution, and the counter ion was changed to sodium ion. The pH of the obtained resin was 8.0.
[0044]
As a comparative example of resin, styrene maleic acid monoester copolymer ammonium salt (Discoat N-14 manufactured by Daiichi Kogyo Seiyaku Co., Ltd.) was prepared.
